Summary: Wheeled forest vehicles have their advantages and disadvantages compared to tracked vehicles. The main advantages are usually attributed to lower weight and higher operating speeds. The main disadvantages of wheeled forest vehicles often include worse cross-country ability, which is associated, specifically with increased skidding compared with tracked vehicles. The article shows that to reduce the negative impact of wheel propulsion system to ensure its effective traction properties when operating in difficult geotechnical conditions on sloping, steep and very steep slopes, taking into account the moisture category and the strength of their constituent soils, it is necessary to take a number of organizational and technical measures. These measures may include zoning the slopes and establishing the categories of soil conditions composing the slope to determine their moisture, strength, deformation and elastoplastic characteristics. Maximum loads on the soil should be set in accordance with the category of its moisture, the parameters of the strength passport and the load-bearing capacity index. In difficult geotechnical conditions of logging and forestry work on sloping, steep and very steep slopes composed of soils of II—IV categories, when a wheeled forestry machine propulsion system may skid its rear wheel axle should be equipped with mono-tracks, and the front axle with antiskid chagreen. |
